When complete control at the lowest level is required, you'll want to use SRP_JSON to create your resource. As noted above, the handle returned by the GetObject service is compatible with the SRP_JSON function and vice-versa. Therefore, a developer can choose to start with either method and continue to use both the SRP_JSON services or and the higher level GetObject companion services (e.g., AddProperty, AddSubProperty, etc.) at will. One unique feature of SRP_JSON is its ability to interrogate the resource object using services like GetValue. This is useful when a resource object is generated elsewhere. For instance, let's assume that a resource object was created by another service and it returns a handle. The calling routine now needs to modify this resource object, but only if it has specific data already in it. The GetObject companion services can only update resource objects, not inspect them. This requires the assistance of one or more of the SRP_JSON member services.
